Specification of Letters Patent.

, Patented Dec. 7, 1915.

Application filed 7, 1914. Serial No. 837,021.

To alt whom it may concern Be it known that I, SIEGM-UND FRANKEL, sub ect of the Emperor of Austria-Hungary, residing at Biala, in the Kingdom of Galicia, in the Empire ofAustria-Hungar have invented certain new and useful Improvements in Bottle-Stoppersof which the following is a specification, reference being had therein to the accompanying drawing.

- The subject matter of the present application is a device adapted to be attached toany ordinary bottle having a flanged or projecting portion around the neck, suchdevice being designed to enable liquids charged with gas or sparkling liquids to be drawn off into glasses without causing loss of gas from the remainder of the liquid contained in the bottle. v 4

The device is characterized by a member forming the housing and fitted with the clamping means for attaching the device; to e the neck, which member is fitted with a part furnished with the washer constituting the gas seal, the outlet conduit and the valve, the said part being pressed against the top of the neck of the bottle by a plug screwed into an internally screw threaded portion of the housing.

A method of constructing the device according to the invention is illustrated by wa of example, at Figures 1 to 4: of the accompanying drawing. These figures show respectively two side elevations at right angles to one another and two sections on the lines A A of Fig. 1 and B B of Fig. 2. Fig. 5 shows the device in use, the section being taken on the line C C of Fig. 1.

The device comprises three essential portions namely: an outer housing n carrying the clamping means and forming the main support of the device, a closing piece 70 provided at the bottom with the plate or washer a forming the gas seal and having the outlet passage and the valve 1" contained therein and a screw plug m which presses on the closing member 79 forcing it against the top of the neck of the bottle and screwing into an internally screw threaded portion at the top of the housing a.

In the method of making the device illustrated in the drawing, the housing a which forms the principal supporting member con sists of a hollow cylinder provided with a slot 0;. The smallest diameter of this cylindrical housing at is somewhat greater than the diameter of the enlarged end it of an ordinary bottles It is'provided in two diametricallyopposite points with downwardly pro ecting arms (z-,0. in which are guided in such a way that they cannot rotate spindles is carrying two curved checks 7', pressed toward one another by fiat springs 25. cheeks are intended to embrace the neck of the bottle beneath the enlarged projecting portion. i

The upper portion of the housing 11. is provided with an internalscrew thread forthe reception of a screw plug m. In the housing a is located a cylindrical block p having a central perforation. This block is provided with a washer p at the lower part, which washer is made of cork and is intended to form a gas and liquid tight seal. Through the washer 'v and the block 39 passes the outlet conduit which projects through the slotw in the housing a, The inner orifice of theoutlet conduit 9 which is situated below the washer '0 is provided with a double clo sure consisting of a bell-shaped valve 1'. This double closure is due to the lower part of the valve r, having a closing disk to which comes against the end of the outlet passage 1, while the upper edge of the bell valve '1' comes against the washer c. The valve r is carried by a spindle 2 which passes through the outlet conduit 9 and extends upward, being pressed upward by the spring cl located in the housing 0.

In the upper portion of the housing a provided with internal screw thread, is screwed a plug m the lower surface thereof acting against theblock p guided in the lower portion of the housing a. The valve spindle passes through a central bore of the plug m.

In order to reduce friction between the plug on and the block 79 guided in housing n projections or feet 0 may be provided at the underside of the plug m coming against the upper surface of the block 10.

The device is mounted and used in the following manner: The apparatus is attached to the neck of the bottle with the clamps f, provided with handles 72., embracing the neck of the bottle beneath the en.- larged portions a.- After this the block 7) is pressed against the top of the bottle neck by screwing down the plug m. and in this way the bottle is closed so as to be liquid and gas tight. When liquid is to be drawn from the bottle, this latter is turned into the inclined position, as shown at Fig. 5, and the valve 1* is raised from the washer 'v The 7 by pressing upon the lrnob at the endof the This raises the valve from the spindle z. 7 7 opening at the end'of the exit orifice, 9 so that liquid can flow out through the outlet orifice under the pressure of the gas in the bottle. When the required quantity has been allowed to flow out, the valve r is released and comes back to the closing position under the pressure of the spring d, but the liquid, remaining in the bell valve 1', atthe moment when the flow is cutoff, is separated from *that contained in the bottle and on turning "the bottle back to the upright position the'inner portion'of the bell valve r being full,as seen at Fig. 4, a siphonlikeclosure is-formed. The gas-contained in the bottle after the'bottle has been turned back into the upright position, 15 not only separated from the outerair, by the two sealing washers, in connection withthe valve, but also by the liquid contained in the valve.

For the washer o, as also for, the disk w,

provided at the bottom of the bellvalve' a material [free from rubber should be emplo'yed,'preferably cork, and for'thevalre, the valve spindle and the outlet passage 27,

p porcelain'china or enameled metal should be Copies of this Patent a be obtained for used, so that the liquid does not come into contact either with rubber or with any metallic part. V

'Having now" particularly described and ascertained the nature of my said invention and in what manner the same isto be performed, I declare that what I claim isr In a bottle stopper, a stopper housing, downwardly extending arms, for holding 7 said housing againsta' bottleneck, an obturating block guided in said housing, a

obturating' block and an upwardly turned bell shaped valve whose bottom acts against the, outlet conduit and whose rim acts against the block so as to form a siphon like seal. I

Intestimony whereof I affix my signature in the'presence of two witnesses.
